This should not be mistaken as connection pooling, per se.
Persistent connections maintain a PostgreSQL backend for each unique
account connecting per httpd process.

3 unique accounts -> 3 backends per httpd.
10 httpd's -> 30 backends.

I second this, or at least patching your sources and reinstalling if you
plan to move to persistent connections under a non-new version of PHP. I
have wasted much first-hand time debugging silly PHP connection messes.

Wow, remember, it is not the size of the .sig that makes the wave; it is
the motion of the ocean. Nine lines? pshaw.
